vTo all whom :it may vconcern Beit known that I, FRANKTHIEL, a citi- Zen of the United States, and a resident of St. John, in the'fcounty of 'Lake and vState of Indiana, have invented a new andr useful Improvement in Means and Methods for Building Silos, of which `the followingis a full, clear, and exactdescription.

means and methods for `bu'ildingsilos, and it consists 1n the combinations, constructions and arrangements herein described and claimed, and in the steps Vhereinafter set forth.

'An object kof my invention is to lprovide meansfor building '.si'los, by theuseof which the lexpense of lerecting' the'ordinary scaf- "folding'of lumber 'is -obviated, as well as the work and'fe'xpensefof againremoving the scaii'olding when'the 'silo is finished. f

. A further object of'my invention is to provide a means 'for erecting silos which comprise a seriesof portable hangers or rsca'iffold unitsthat are yraised as' the struc- Tture is progressively built up and whlch form supports lfor workmen and material;

A further objectyo'fI my invention is to provide means for building silos which, when'. the 'silo is built,` may Ebe lowered and used over and'over again undersimilar circumstances.

A furtherobjeot'of my invention is to provide process, by "means of which'the expense in building fs'ilos'. is materially reduced-and in which the'labor is cut down to arninimum'.r""

Other objects and ladvantages willappear in the following specification, and the novel features 'of fthe' invention will be particularly `pointed out in lthe appended claims My invention is illustrated "in `the taccompanying drawings,forming part of this application, in which- Figure l is a top plan view of ythe silo and scaffold, Y Y

Fig. 2 is a side viewof the top portion of the silo showing one scaii'old,

Fig. 3 is a side view of the top portion of the silo showing two scaffolds, and

Fig. 4 is .a perspective view of one of the units of the scaifold.

The present invention is designed to facilitate lthe building of silos of the type in which there is "as circular wall of strips 3 which are disposed vertically. These strips are made preferably in 10 foot lengths, but

5 feet.

upper ends disposed on the line substantially in alinement and the upper ends yof the next lower row terminating short ofthe first named row, thereby forming spaces?)a between the boards 3. After a row of boards is added, the wall 2 is built up a correspondl ing distance. Y `When the building of the silo ha-s prolgressed so far that the builders cannot reach high enough to work,- a portable scail'old is provided upon which the builders may continue to build .thefsilo y sists of four similar removableghangenunits placed across the top of the partly completed silo and boards plaid yacross the ends of the units lto forma platform.

adjacent strips are lapped for a distance of 'l In other words, a circular row lof` vertical strips is formed by alternating boards, while 'the next higher row is com- `posed of intermediate boards having their feet above the upperends of the adjacent lower row. My invention relates to improvements in This scaifoldjcon- Each unit consists ,of a main supporting member 4 having bolted to it .at each end porting ,member, fand the members 5 ,and 6 "preventing, the `dislodgment of i the foot board by lateral movement. Twofofthese units'arelaid'parallel vto each other across the top ofthe partly completedg'silo, and-the anglesvto the first two' (see l). v',"The members .t-of the lunits rest onthe tops of 'the next tothe last'row of" boards vv3 and between 'the extending.,halves of the last row ofboards 3 (see Footlboards V8 are placed from the-ends of voneunit to the other. This formsv a platform around the outside of the silo on which the builders can work.

Let us assume that the silo `has been built up far enough for the first portable scaffold to be put upf` First the four similar hanger units are laid across the partly completed siloas stated above. Then the boards 8 areV placed around the silo on the members 7 (see Fig. 2). This forms a platform by means of which the tile wall is built. Material is hoisted on the platform and the Vtile other two are laid across the silo atright f wall is built upto the level of the mem- Vspaces, where the members 4 are placed, the

boards 3 are leftv out until after the scaffold has been removed.

To proceed with the building of the silo, a second portable scaffold is used. Thexsecond scaffold is ksimilar to thescadold described. The four units of the second scafffold are placed in position on the silo (see Ifigs. 1 and a step higherthan the first scaffold, which is equal to one-half of the length of the boards 8. The boards 8 are then placed on the ends of the members 4 of the second or upper scaffold", as shown in .Fig 3. The four units of the lower scaffold are now ready to-be removed. To remove the hanger units of the lowe scaffold, the builders let down a rope with a hook attached to it, and lift one unit out at atime through the space between the boards 3. yThe units of the lower scaffold are then placed on the retaining' bolts 9, as shown in dotted lines in Fig. 3, the bolts 9 being secured to the members 6.

After the lower hanger unitsl have been disposed on the bolts 9, the boards 3 are driven in theV spaces in which the members 4f of the units were placed. The boards 8 are then taken from the ends of the members 4 and placed on the members 7. Material is again hoisted and the builders build the tile wall up to the level ofthe members 4. The boards 8 are then positioned on the ends of the members 4. Material is hoisted on the platform formed by .the boards 8 on the ends of the members 4, and another row o f the boards 3 is added to the wall 1. The boards 3, for the spaces 'in which are positioned the members 4, are driven in after the members 4 are removed. Y

The scaffold is now not high enough to proceed with the building .of the silo. The

lhanger units of the scaffold, which are hanging on the retaining bolts 9, are lifted up and placed in position across the siloone step higher than the vscaffold on which the bullders are Working. The same method for f ing between adjacent sockets.
